Thrassian Atoll Posted February 23, 2019 Share Posted February 23, 2019 I have tried everything to get this Probe to act right. I have calibrated multiple times, made sure no bubbles in it, etc. I even bought a new Probe a couple of weeks ago thinking it was the Probe that was bad. The numbers are always spot on after I calibrate it but a day or 2 later and they are all over the place. The readings will be anywhere from 40 to 25. I don’t even care if the numbers are spot on accurate, I just want them to not jump all over the place. Anybody have ave any ideas on how to fix it? It’s in my 25g lagoon in a Probe rack with the other apex probes. All of the other probes work fine. Quote Link to comment

I might just just have to ignore it. I know people are always having issues with it being accurate compared to a refractometer, but I haven’t heard of many issues with it being all over the place.

vegasgundog Posted February 24, 2019 Share Posted February 24, 2019 Refractometer is always going to be best bet, but your can't even rely on apex as a fail safe say the ato goes crazy if the probe won't stay in one spot. 1 Quote Link to comment
Tom@HaslettMI Posted February 24, 2019 Share Posted February 24, 2019 Do you have the temp probe plugged into the PM2 and temperature compensation turned on? Tom 1 Quote Link to comment

Yeah, that’s the only thing I really want it for. Like if the ato stays on for whatever reason. Quote Link to comment

Tom I am not running an extra temp Probe, just the one it comes with. I keep the temp comp at the 2.2. I have also tried just using the tank water to calibrate the Probe. That doesn’t help keep the salinity readings consistent either. Quote Link to comment

Or are you running the newer APEX? 1 Quote Link to comment
Thrassian Atoll Posted February 24, 2019 Author Share Posted February 24, 2019 My only guess would be some type of interference with the other wiring, but I feel like that would mess with the other probes as well and non of them ever act weird. Quote Link to comment

I’m still Classic APEX with the PM2 module. Sounds like interference is the most likely culprit. Can you isolate the salinity probe wire to see if that helps? Tom 1 Quote Link to comment

I am gonna move it to a different spot in the Probe rack and see if that helps. I had it in a different spot before. Maybe bubbles are getting in it or something. Quote Link to comment
OldManSea Posted February 24, 2019 Share Posted February 24, 2019 I had this problem as well (Apex 2016). I was told to run the wire far away from any other wires. I routed it away from everything else and that helped enormously. Once in a while it goes crazy for a couple of hours but then comes back to where it typically is. Not something I pay a lot of attention to since it is touchy. 1 Quote Link to comment

I am going to try and isolate it the best I can. It’s actually resting on my light wiring right now and I know I can at least get it away from that. Quote Link to comment
Thrassian Atoll Posted February 24, 2019 Author Share Posted February 24, 2019 So moved the salinity probe a couple spots over in the Probe rack, rerouted the wire and recalibrated. See how this goes. 1 Quote Link to comment
Thrassian Atoll Posted February 26, 2019 Author Share Posted February 26, 2019 So in the past 48 hours since I moved the Probe over to a different spot in my Probe rack and isolated the salinity probe wire, the numbers have been spot on. After a week or so I’ll let you know if the numbers are still consistent. 2 Quote Link to comment
Thrassian Atoll Posted March 13, 2019 Author Share Posted March 13, 2019 Salinity numbers have been reading perfectly over the past few weeks since I made the adjustments. I am going to go ahead and say it’s working fine now. 1 Quote Link to comment
OldManSea Posted March 13, 2019 Share Posted March 13, 2019 Congrats! Getting the wire away from all the others worked wonders for me as well. 1 Quote Link to comment
Tamberav Posted March 13, 2019 Share Posted March 13, 2019 ooo just saw this post, was going to say it can't be near any pumps or wires but looks like you fixed it 👍 I think I may just sell mine and the ORP... cuz I really just don't care about either and I am turning into a clutter hater. 1 Quote Link to comment

I am starting to get pretty cluttered with everything. Going to be even worse when I have the trident shoved in my stand. 😂. Orp is pretty worthless. Reading about it makes it even more confusing.
